Differences from Official Compendium

This downloader will create new data columns for easier data filter:

• Race: Origin (and keywords).
• Background: Benefit (Replace Associated Skills).
• Theme: Prerequisites.
• Power: Type (Frequency + Type) and Keyword.
• Feat: Prerequisite.
• Item: Split into 4 categories (Item, Weapon, Implement, and Armor). Add Type column.
• Companion: Size and Type.
• Monster: Size and Type.
• Terrain: Group and Level. Combine with Trap to control category count.

Many existing columns are also enhanced or corrected, such as multi-source classes.

Let's face it, the official compendium has errors. This downloader fixes over 1560 entries during export:

• 187 entries moved to correct category. (Superior implements, Lair items, Assassin's poisons, Consumable wondrous)
• 150 items missing power frequency. (Dantrag's Bracers, many energy weapons, dragon orbs, light sources etc.)

• 35 entries that wrongly says "basic melee attack". (Bane's Tactics, Feral Armor, Dancing Weapon, Kobold Piker etc.)
• 24 entries with missing/wrong content. (Kord's Relentlessness, Rings of the Akarot, Hybrid Vampire Surge etc.)
• 23 entries with formatting issues. (Mirror of Deception, Silver Hands of Power, etc.)
• 10 typos. (Cambion Stalwart "bit points", Primal Grove "grp", Rubble Topple "Singe", Essential hybrid sourcebook etc.)
• 2 new entries (Artifact and Item Set.)
• 204 entries with other inconsistent content. (Winged Armor type, Xenda-Dran Array tier, Racial power without type etc.)
• 94 entries with missing listing data not caused by above issues. (Subrace abilities, Heroic feat tier etc.)

Developer's Guide

This program has two parts: a downloader that fetch and export data, and a viewer that browse exported data. The downloader will embed the viewer on build, so that there is only one deployable file.

• The development branch is less vigorously tested but usually have more features and/or fixes.
• Downloader source code is in java folder, and use libraries in java_lib folder.
• Viewer source code is in html folder. It is built with CocoDoc, also in java_lib.
• Both use resources at the root (license) and in the resource folder.
• Use Ant (build.xml) to 'make' an executable jar. The make_exe target depends on Launch4j.
• The jar can also be extracted to a new project folder; use Ant to move the extracted files back to original structure.

SQLJet is used to access sqlite database, but the data cannot be read by other SQLite libraries. It may be a sqljet issue. Since it is very light and has no other issues, I'm keeping it and hoping someone can find what's wrong someday.
